[PATCH v3 bpf-next 06/10] bpf: Expose symbol's respective address

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since different symbols can share the same name, it is insufficient to only
expose the symbol name. It is essential to also expose the symbol address
so that users can accurately identify which one is being probed.
